The sack 11 is, for example, filled with 160 g of this oil / water emulsion ₀ during the round 15 between this sack and the container is filled with 40 g of a mixture of n = butane imu is © = butane { is filled with a gas pressure of 2 _a 4 atmospheres at 20 C).

Active ingredient concentrate and propellant gas cannot be sprayed without the use of a sack 11, because without a partition the propellant gas is emulsified into the active ingredient concentrate and a · dense foam escapes when the valve is operated »
